AP US History Unit 1: Period 1, 1491–1607

In a single century, the Atlantic stopped being an ocean nobody crossed and became the busiest highway on the planet. Native American societies who had farmed, traded, and governed the continent for thousands of years now contended with European empires, African captives carried in chains, and a flood of new crops, animals, and pathogens. The collisions of Period 1 produced the demographic, economic, and cultural map on which all of North American history would be drawn.
